I oolvfninnn METAL-WORKING MACHINE.

Application filed Tuly 25, 1925. Serial No. 46,173.

The machine herein shown and described constructed and operated so that it may do a wide variety of work, particularly drilling, spinning, riveting, punching, hammering and tapping.

- operated by foot.

The object of the invention is to provide one machine which is readily adaptable for drilling, spinning, tapping, riveting, punching, hammering and like treatment of metal. One feature of the invention .is-the provision of means for operating the spindle so that it may be simultaneously rotated and vertically reciprocated, or only vertically reciproeatedfor only rotated, as desired for the particular work in hand, and particularly in constantly driven machines. In addition to the foregoing there is the provision of levers for varying the speed of the means for reciprocating the spindle to adapt it for drilling or riveting or other variety of work, along with the associated means for operating the spindle. Still another feature is the adjustable eccentric or cam construction for reciprocating the spindleand controllingthe extent of the actuating movement thereof.

The full nature of the invention will be understood from the accompanying drawings and the following description and 30 claims: I In the drawings, Fig. 1 a central V81 tical sectionthrough the machine, cent-rally.

Fig. 4 is a section on the line 4- l of Fig. l,looking downward, parts being broken away. Fig. 5 a front elevation of the cam mechanism for operating the spindle with the parts shown on a largerscale and in altered position from the position shown in Figs. 1 and 2.

This is a power machine and the form herein shown is operated by foot. The pedal 5 10 is on a pedal lever 11 fulcrnmed'at 12 in the base frame 13 and the pedal is held in elevated position by a spring 14 which is connected with the inner end of the lever and to the base frame at The pedal lever is pivoted to the lower end of a vertically movable rod 16 that extends up within a tube 17, which at its lower end is secured by rivets 18 to the base frame 13 and on its upper end there is atubular frame 19.

I The tubular frame 19 has an upper fixed It is a power machine ciprocate vertically, does not move vertlcally as it is between the arm or jaw 20 and under it a vertically ad-' justable armor jaw 21 which carries in its outer end a member 22011 which the work is mounted that is to be treated. Substitute forms of the member 22 are employed according to'the character of the work to be treated. Thelower arm 21 is-secured to the tubular frame 19 by bolts 23 extending through slots (not shown) to permit the vertical adjustment of the arm 21. p

.The fixed arm or jaw 21 carries in its outer end a vertically reciprocable spindle 25 which is in line with the center of the member 22 on the lover arm 21 and a tool of any desired type is mounted in forcarried by the lower end ofthe spindle for treating the work on the member 22. I Said spindle is rotated when desired by a spiral gear 26 splineo thereon so that the spindle'may rewhile the spiralgear 26 upper part of the arm 20 and the housing 27 secured thereon by screws 28. The spiral gear 26 is driven by a spiral wheel 29 locatedbetween the arm 20 and housing 27, as shown in Fig. 1,.and mounted on a shaft 30, as shown in Fig. 4. This shaft is mounted on the upper arm 20and with its outer end in a bearing on the outer end of an arm 31, by a gear 32 splined and slidable on the shaft which motor shaft 34 which is driven by an electric motor 35 carried by an arm 36 extending to the right from the main arm 20, as appears in Fig. 2. The gear 32 is moved into and outof meshwith the gear by a handlever-37 pivoted at 38 on the frame arm 31, asseen in Figs 4. By this means the spindle may be caused to rotate or notto rotate as desired. f The vertical reciprocation-ofthe spindle is effected by the following means: There is a housing. 40 at the upper end of the" machine which extends up from the housing plate 27 heretofore mentioned. A horizontal shaft 41 is mounted therein, one end of said shaft having bearings in'the end of the housing 40 and the other in a rib 4-2 extend ingup from the bottom of the'housing, as seen in Figs. 1 and 3. There is splined or slidably mounted on the shaft ll a hub 43 carrying a; large spurgear 414 and 'a small spur gear 45. These" gears are shifted by a hand lever 46 pivoted ate? in the housing as seen in Fig. 41. Itis driven Y is driven by a gear 33 011 a I 46 and the inner end of the lever is connected 43. This enables the by the gear 45 when it is in mesh with a gear 48 on a parallel shaft 49m said housing 210, as shown in Fig. 3, or by the gear 44' when it ismoved' into mesh with a small gear 50 onthe shaft 49.. By this means a change of speed is obtained, the large gear 44 driving theshaft 41 at-a low speed and the smaller gear 45 driving it at a higher speed; The shaft 49 is' driven by a bevel gear .51 OlliillG'SllitfhdilfiDd a bevel gear 52 on a shaft 53 and mounted in the housing 40 at a right angle to. the shaft 49 as seen inFig. 3. The shaft 53 is driven by a'sprocket wheel 54, sprocket chain 55 and sprocket wheel56, the latter being mounted with the gear, hnb

shaft 41 to be drlven onthe motor'shaft 30, as seen in Figs. 2

and 3. V a

The foregoingmeans drives the shaft 41 constantly and when desired it drives a shaft 60 mounted in the housinglO in alignment with' the shaft 41, asseen in Fig. 1. I To this end, the twoshafts are clutched by a clutch member 61 on the driven shaft 60 being moved into clutching engagement with a clutch member 62on the shaft 41, by a clutch lever 63, which is operated by a connecting rod 64 mounted in a bell crank 65 fulcrumecl at 660m an arm 67 extending up from the housing plate 27 heretofore described. The other arm ofthe bell. crank lever 65 is pivoted 'at 68* to the upper end of the pedal-actuated' rod 16, heretofore described. Hence, when the pedal 10 is depressed, the two shafts l and 60 will be clutchedtogether andywhen the pedal lever 11 is released, the spring 14 will, through the intervening mechanism, release the clutch members 61 and 62 sothat the shaft 60 will stop. 1

The shaft 61 vertically reciprocates the spindle 25,as shown in Fig. 1. Said shaft 'Mld has secured on its'outer end an eccentric 70 and said eccentric has mounted thereon an eccentric strap 71' which is secured to the eccentric by a screw. '72 which extends througha slot 73 in the eccentric strap that isgconcentric withthe axis of the eccentric 7O the screw 72; screwing into the eccentric. Thusfthe stroke of the eccentric strap construction is readily predetermined by releasing the screw 72 and angularly adjusting the eccentric strap 71 on the eccentric 70 to the desired position, and then tightening the screw 72. The slot 73 is substantiallys'emicircular" so that theeccentric strap can be changed from the 'position shown in Figs. 1 whichgives the extreme throw ofithe eccentric strap, to the position shown in Fig. 5, which gives the minimum throw of the eccentric strap; I

The cam 71' has mounted on it-an upper circularend of a member 74 which is pivoted atj75 to a ball'racecap 76 in which the upper end v ofdhe spindle 25 rotatably crate continuously and 41 constantly.

spindle 25 to rotate, the lever 37 shown in Fig. 4, is operated to bring the gears 32 and 33-inanesh, as they are shown. If it is'dcsired that the spindle 25 shall not rotate, the lever 37is operated to disenga from gear33. Then the she t 30 will not operate and the spindle will not rotate.

When it is desired to reciprocate the spindle vertically, the pedal lever 11 is. operated'by foot which clutches shaft 41 with shaft 50, but if it be desired not to operate the spindle, the pedal lever is not operated. Therefore, with this machine the spindle can be vertically re'ciprocated while bein ro tatedor while. it is not rotated and the spindle can be rotated while it is vertically reciprocated on not reciprocated. The cc centricv strap 71 is adjustedin any position on the eccentric 70 to obtain the desired throw or vertical movement of the spindle 25. The vertical adjustment of the arm 21 carryin the work also, in addition to the means. orcontrolling the vertical throwof the spindle, gives to the machine a wide range of operation. If onedesires to drill, a suitable drilling tool is secured to the lower end of the spindle 25. The gear 32 is put in mesh with the gear33so that the spindle, as shown in Fig. 4, will rotate. The handle 46, shown in Fig. 3., isgoperated to move the large gear 44: on the shaft 41 into mesh with the gear 48 soas to reduceto the minimum thespecd of rotation ofthe shaft, 41. Then the pedal is operated to clutchthe' shaft 60 with'the shaft 11 which will cause a very slow verti:

e the gear 32 followed exceptingthat a spinning tool is secured to thelower. end of the spindle 25: While tapping the same procedure is followed excepting a'tapping chuck isused. If i one desires to rivet, the gear 32 is thrown out of mesh with the gear 33, so that the spindle does not rotate. The handle 46 is operated to bring gear 45 into mesh with gear 48, as shown in Fig. 4, to obtain high speed of the shaft 41. Then the pedal lever 11 is operated to chitch shaft '60 with shaft 41. This will cause a rapid vertical reciprocation of the spindle 25 to the" lower end of which a riveting tool is secured. This will give .straight rapid blows for upsetting the head of a rivet. iVhile punching the same procedure as in riveting is employed, except-ing the necessary change of tool, and the same is true while hammering.

While the machine shown in the drawings illustrates this invention, the invention is not limited to the details thereof as they may be varied without departing from the spirit of the invention.

The invention claimed is:

1. A combined metal working tool of the kind described, including a frame, a p1u rality of constantly driven shafts, a tooltively connected and said constantly with said spiralgear, a shaft on which said spiral gear is mounted, a constantly driven' shaft, means for gearing said two shafts so that they maybe operadisconnected, a shaft operated means for vertically reoiprocating the spindle, a constantlydriven shaft in alignment with said last-mentioned shaft,
